253171 - Mozilla should prevent losing data when the disk partition runs out of space

Status: RESOLVED DUPLICATE of bug 246675

(SeaMonkey :: Bookmarks & History, defect)

Description

[Oscar Manuel Gómez Senovilla]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; es-ES; rv:1.7) Gecko/20040616
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; es-ES; rv:1.7) Gecko/20040616

A user in my machine (debian system, mozilla 1.6) happened recently that had a
lot of info in his profile, such as bookmarks, history, etc (the mail was imap,
so luckily there was no change on this). He was working visiting pages, adding
bookmarks, etc. Another user started downloading a big file, and this user
didn't calculate disk space, so apart his download finally failed, the partial
file remained there until I deleted it. Later, the other user told me that he
had lost his bookmarks and history (as I can remember). I checked everything I
could and saw that the bookmarks.html was very low in size, and there was no
backup AFAIK, so his bookmark collection couldn't be regenerated.

Reproducible: Always
Steps to Reproduce:




I think mozilla should check if any write it performs is successful before
deleting the original file, so at least, if there are any problems, not lose any
existing data.

I have seen several bug talking about similar situations, but I haven't seen any
talking about preventing data loss or losing bookmarks, so I file this as new
because I haven't seen faced what I find important.

Thanks, Michiel. The Summary ("create a non-overwriting file output stream") 
didn't help at all :)
